MARTIN S. CRANE, OF HOBOKEN, NEW JERSEY.

Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed July 9, 1909. Serial'No. 506,717.

To all whom it may concern:

Be it known that I, MARTIN S. CRANE, a citizen of tlie'United States of America, residing at h )boken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Devices for Securing Together Glass Plates for Store-Fronts, &c.; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in devices for securing together glass plates for store fronts, show cases and the like.

One of the objects of the invention is the provision of a device of the above character which is simple in construction which will hold the plates securely in position, and which is neat and ornamental in appearance.

A further object is the provision of a securing device including an outside corner strip which will be held firmly against the two glass plates without the necessity for clamping members or clamping devices of any kind which extend through or engage the outer surface of the corner strip.

The invention may be briefly summarized as consisting in certain novel details of construction and combinations and arrangements of parts which will be described in the specification and set forth in the appended claims.

In the accompanying sheet of drawings Figure l is an outer or front elevation of the two glass plates held together by my improved plate securing or uniting device. Fig. 2 is an inside or rear elevation of the same. Fig. 3 is a transverse section sub stantially along the line 33 of Fig. 1.

The glass plates may be arranged at any angle to each other and with a slight modification of the securing or uniting means, they may be arranged in the same plane or in line with each other, but I have here shown them at right angles to each other.

Referring now to the figures of the drawings l0 and 11 represent respectively two glass plates which are arranged with their adjacent edges a short distance apart, the edges in this case being square or at right angles to the inner and outer surfaces of the plates. Bridging the space between the two plates and overlapping or embracing, and in this case, hearing directly against the outer surfaces of the plates, is an outside corner strip 12 which is preferably formed of sheet metal, and is provided with two side portions 13 and 14 arranged at an angle corresponding to the angle made by the two plates, the apex of the angle, formed by said side portions, being on a line midway between the adjacent edges of the plates. Each side portion of the corner strip is provided with an integral inwardly projecting flange between the apex of the angle and the outer edge of such side portion, the two flanges extending lengthwise of the strip along and adjacent to the edges of the two plates respectively, and each flange is preferably formed by bending the metal inwardly and doubling the same upon itself so as to consist of two thicknesses of metal. The two flanges are preferably arranged at right angles tothe respective side portions 13 and 14 of the corner strip so that they 'will be parallel to the square edges of the plates and will therefore be convergent. It may be here stated that these flanges are designed to be gripped by clamping members which are drawn inwardly by a suitable member forming a part of the clamping means so as to hold the corner strip firmly against the outer faces of the two plates.

The clamping devices, which are employed in conjunction with the outside corner strip, are arranged at intervals along the length of the strip and will now be described. Each clamping device includes a clamping member 17 which is located between the flanges 15 and 16 and is preferably in the form of a block which conforms substantially to the shape of the space in the corner of the clamping strip between said flanges, and is provided with convergent faces which are parallel to and are adapted to engage respectively the adjacent or inner faces of the flanges. Extending inwardly from the clamping member 17 between the adjacent. or inner edges of the flanges, is a tension member forming a part of the clamping de vice, and consisting in this case, of a screw, belt or pin 1'7 preferably threaded throughout its length, the outer end of said member being screwed into a threaded socket in the block and thereby secured to said block. Other means for securing this member to the clamping member 17 may be employed, however. The outer faces of the flanges 15 and 16 are engaged by a clamping member 18 which cooperates with the clamping member 17 and consists preferably of a plate having end portions 19 and 20 which are located between the flanges and the adjacent edges of the plates and engage the same. These end portions, therefore, form seats or abutments for the edges of the plates. This clamping plate 18 has a portion intermediate the end portions 19 and 20 and this intermediate portion is provided with an opening through which the bolt or threaded pin 17 extends. The flanges 15 and 16, which, as was stated before, are integral with the corner strip, are clamped tightly between the clamping member 17 and the clamping member 18 by means of a nut 21 on the'bolt or threaded pin 17. It will be seen from the construction so far described that When the flanges are clamped between the members 17 and 18 by tightening the nut 21, the bolt or threaded pin 17 is firmly united with the corner strip and when tension is placed on said member 17 the corner strip will be drawn against the outer surfaces of the plates without any possibility of bending or spreading said .flanges l5 and 16. Each clamping device also includes an inner clamping member 22, also preferably formed of sheet metal, and having two end portions 23 and 24 which embrace and preferably bear directly upon the inner surfaces of the plates and an intermediate portion 25 having an opening through which the bolt or threaded pin 17 loosely extends. A nut-26 is provided on the outer end ofthe bolt'or threaded pin 17 and when this nut is tightencdaga'inst the intermediate portion 25 of' the inner clamping member 22, the latter is forced outward against the plates and the corner strip is drawn inward, thereby providing a rigid clamping device.

I do not desire to be confined to the exact details shown, but aim in my claims to cover all modifications'which do not involve a de- 1 parture in the spirit and scope of my inventiOIl. 3
